Something of a stoic, Robert Mandell described him as being a "West-Point-mentality soldier. He is always doing things by regulations... Zach was never our most colorful character and we played off that quality ... he comes from a world of perfect order, he likes to see things in certain ways, but in reality, nothing works that way - especially in the whole new universe he now can explore."
During the escape from Kidd's ship in Phoenix, Zachary was critically injured. In order to save his life, almost his entire left side was replaced with bionic implants. "We wanted Zach to have his own personal conflict and that turned out to be his bionics," Mandell explained, noting a certain irony. "He never really trusted machinery or hardware, but then he has an accident where suddenly, it is machinery and hardware that saves his life. Now, he has this internal conflict with how to deal with his own bionics." Zach's implant is linked directly to his bionic left arm and leg.
FANFIC NOTE: Between the loss of his wife, and the conflict with the bionics, Zachary is seen by some fans as a very tragic and troubled figure, holding onto things for the sake of Zach Jr. and Jessica. A few fans even paint the character as clinically depressed.
